The answer depends on a lot of factors e.g. where are you based? Some states in the US allow you to do whatever using your own resources and your own free time. Even though it might be legally allowed, companies' contracts generally forbid you from doing anything competitive. So:
- Are you doing this using your won resources and time?
- Are you building a potentially competing product?
- What does your contract say about it?
- Can anyone still claim IP on what you've built so far? As in it seems you worked for someone before to build it, did you get compensated for it?
Of course, IANAL, so you'd want some professional advice.
